I'm trying to understand something when exporting map as PDF file in Esri's ArcGIS for Desktop.
The ability to choose paper size.
The ability to choose DPI.
Thought that those are printer parameters. Supposedly when I export a map to the computer the only parameters whom need to set are paper ratio and pixel number for chosen ratio.
Before exporting I will check if my screen can handle this amount of pixels on this ratio (DPI and screen size) and my printer with this amounts of dots on a given paper size (DPI).
So DPI and paper size are properties of the printer not of the PDF file itself.
